Fig. 23 is a plan View of the packageafter the Wrapper has beencrimpedand sealed;

Fig. 24 is a section online 24T-24 of Fig. 23. In Wrapping many articlesit is desirable to seal the articles in a package which is airtight inVorder to properly preserve the Wrapped article. WaXed or paraflinepaper is commonly used for providing an air-tight wrapping but in orderto make the wrapping really tight itis necessary that there shallbe no.unsealed folds aording passage tothe interior of the wrapper.

In the present 'invention the wrapper is folded jbout the article withthe edges overlapping on three sides of the article and extending faceto face and the overlapping edges are then sealed together by theapplication ,of heat which partially melts the paraiiine and the meltedparaiine is then chilled to completely seal the contacting faces of thewrapper. The Wrapper thus sealed-is illustrated in Figs. 23 and 24 ofthedrawings. i

l The projecting edges are then 'folded against A'the portion of thepackage containing the wrapped article. By sealing the edges of thewrapper while they project away'from'the karticle it is possible toeffect the seal with-A portion out subjecting the article to the heat ofthev sealing irons.v It is also possible to insu-e'4 uniform pressureagainst the portions of the wrapper to be sealed which cannot be donewhere it is attempted to seal the flaps against -the sides of thewrapped article. By way of illustration a machine is shown in the draw?11m i ings for wrapping candy chewing gum briquettes, but it will beunderstood that the invention is not conned to a machine `for wrappingparticular articles, but may be applied to wrapping a large variety ofcommodities.

In the drawings,the numeral designates the base or supporting frame fora wrapping machine having a driving pulley 31 which may be driven fromany suitable source of power. The pulley 31 is connected by a belt \32to a pulley 33 on a shaft 34 and the gearing 35 connects the shaft 34with the main drive shaft 36. The drive shaft 36 may be provided with ahandle 37 by means of which the machine can be operated by hand forinspection or other purposes, when desired.

At the top of the frame 30 is a hopper 38 in which the briquettes to bewrapped are placed. Suitable feed rollers and agitating mechanismV areprovided at the base of the hopper 38 driven by a belt 39 extendingupwardly from the shaft 34. The briquettes are directed from the hopper3 8 into downwardly extending guideways 40 and 41 in which the 'edges ofthe briqucttes travel in grooves in guide bars 42, 43 and-44, asillustrated more clearly in Fig. 3. Positioned below the lower ends ofthe guideways 40 and 41 is an assembling wheel 45 having disc portions46 and 47 differing in diameter so that the disc 46 pro-L jects radiallybeyond the disc 47 by anamount eqlrllllal to the length of one of thebriquettes w ch are snown at 48 in Fig. 3.' The discs 46 and 47 areprovided with radial grooves 49 and 50, respectively, into which thebriquettes enter from the lower ends of the guideways 40 and 41. Thegrooves 49` and 50 extend inwardly to the same radial distance from theaxis of the wheel 45, the depth of the groove in the disc 47 being equalt^ the length of one briquette, while the dept;L of the groove in thedisc 46 is equal to the length of two bri- -quettes A circular groove 51extends inwardly'from the outer lateral face of the disc 46 and abracket 52 is mounted on the sup-v porting` frame 30 and provided withan ar- 'cuate fiange 53 which extends into the groove 51 and has itsouter face Hush with the 'outer I periphery of the disc 47. It will beappar- .ent that the briquettes entering the groove 49 in the'disc 46will be arrested by the flange 53 'so that asinV lebriquette will beadmitted at one, time an will be. held by the flange 53 with,its inner.end in registration with the, briquette inthe groove 5() of Y outer endof the rIhewheel 45I intermittently rotated by 4"90 steps and betweensuccessive-rotations is brought to rest with the radial grooves in regIistr'a'tion with the guides 40 and 41. Each time the wheelcomesto .resta pai-r of briquettes are deposited in the grooves registering with theguides40 and 41 and at the nextrtation the briquettes are brought to aposition on a level with the axis of the assembling Vwheel and arearranged flat side down, as shown at the left in Fig. 4.v The wheel 45may be rotated by any suitable driving mechanism, such as a lever 54engaging a ratchet wheel 55 on the shaft 56 which supports the.

wheel 45. The lever 54 is oscillated by a rod 57 operated by a cam 58 onthe main drive shaft36. The mechanism may be timed to impart a-.quarterof a rotation to the wheel- 45 for each revolution of the drive shaft36. A receiving platform 59 is mounted on the frame 30 and has its uppersurface disposed in registration with the lower `faces of the briquettcs48 held in the slots 49 and 50 extend-v 2,'and oscillated about itspivot by a link 63y secured to an arm 64 which is pivoted at 65 on theframe 30 land provided with a cam roller 66 which engages a cam groovein a cam wheel 67 secured to the main drive shaft 36. The arm 61 istimed to oscillate during the pause in the rotation of the wheel 45 andthe movement of the finger 60 brings the two briquettesinto alinementwith each other and transfers them from the wheel 4 5 to the platform59. A guide plate 68 is spaced above .the platform 59 and carries guidemembers 69 into which paper wrappers 70 are fed in a vertical positionby any suitable paper feed mechanism, not shown. The briquettes 48 aremoved forwardly on the platform 59 by the finger 60 until they pass thetransverse. ning for the wrappers 70, asillu'stratedzin ig. 7. This willfold the upper and lower edges of the wrapper 70 backwardly againstthetop and bottom faces of the 'briquette's and draw alle., folded napsinto-the opening between the y platform 59 and upper guide 68.. When thefinger 60 is returned the briquette will be de he platform 59 isprovided with and 7 2 over which the briquettes 48 aremoved posited inthe opening between theplatform Vbythe iingerGO. .An arm 73 is pivotedat 74 on a horizontally extending arm 75which in turn I'is pivotallymounted at 76 'on the' frame 30and oscillated vertically by acam 77 onVVVthe shaft 36.-v The arm 73 is connected by a link 78 on the larm 64sothat both vertical and horizontal movement is imparted to the arm 73.The arm 73 carries a pair of fingers 79 and 80 which are pivoted at81 onthe vend'ofthe arm 73 and are spaced apart to register with the slots 71and 72 in the plat- -form 59.- The fingers 7 9 andl 80 are resilientlyheld'b'ysprings 83 which tend'to rotate the top ends ofthe fin ersforwardly or to the right, as viewed in ig. 7. -The movement of the arm73 projects the fingers 80 upwardly through the-slots 71 and 72 in therear of the briquettes after the finger has been withdrawn, leaving thebriquettes in the foremost position to which they are moved by thefinger 60. Each of the fingers 79 and 80 is provided with a forwardlyprojecting noseiece 84 which enters between the baekwardly irected flapsof the wrapper and engages the rear edge of the briquet-te. Theiingersare then moved'forwardly and discharge the briquettes from the forwardedge of the plat-` crimped at their ends bycrimpingplates 86, one ateach side of the lturret 85. The crimping plates 86 are carried on'leverarms 87 which are piv'oted on a st-ud "shaft`88 pro-y jecting outwardlyfrom the machine frame.

` rearwardly to engage thefolded edge of the vwrapper and press thefolded portion backwardly between the end flaps, as indi' cated in Figs.16 and 21. The rear contact edges of the crimping plates 86 are beveled,

as indicated at 92, tofacilitate the crimping action of the'plates onthel wrapper.

After the briquettes are positioned in the Docket of the turret and thengers 80 and crimping plates 86 have been withdrawn; the briquettes willbe carriedupwardly in the direction of the( arrow in Fig. 7 by rotationof the turret. It will be noted that the platform 59 projects beyond theupper guide member so that the briquettesneed, not be dischargedentirely from the supporting plat-. lform to permit Athem to be liftedby rotation' pf the turret. `T he pockets in the turret are formed byvfixed contact members 93 and Aspringheld clamps Y94. VThe clamps 94 areshorter, than the members 93 and the members 93 may be -provided ,withrecesses 95, as. shown in Fig. 9, to pass the'projecting end of thecentral supporting portion 96 of the supporting platform 59. When. theVbl'iquettes` areclamped bythe jaws 93 and 94, rotation of the turretwheel will'lift thev Etiquettes fromA the' support 59.

The shaft 86 which ca 'es the turret wheel 85 is driven by 'a Geneva.drive comprlsmg an al'm 9 7 mounted on- :r' shaft 98 and having a collar99 for holding the driven member ystationary in its various stations.The driven member 100 is secured lto the shaft 86l and is provided withslots 101 for receiving a roller 102 on the arm 97 and with arcuaterecesses 103 for engaging the collar 99. The 'collar 99 is provided witha cut-away portion `1.04 to permit thebifurcations forming the recesses103 to pass the collar during rotation of the driven member by theroller 102. The shaft 98 is driven by a sprocket wheel 105 operated by asprocket chain 106 which passes over a driving 'sprocket 107 on the maindriveshaft 36. The sprockets 107 and 105 are of the same size so thatthe turret 85 is rotated one step ,l

for each rotation of theniain drive shaft 36. This brings a new pocketinto registration with the supporting platform 59 for each pair ofbriquettes discharged from the platform. After the briquettes are liftedfrom the supporting platform 59y and transferred to the first station bythe vturret 85, the turret rel mains stationaryA while the edges of thewrapper are sealed by a sealing clamp located adjacent the first stationstop of the turret above the platform 59. This sealing clamp comp-risesa pair of jaws 108 and 109 shown in open position in Fig. 7 'and inclosed position in Fig. 1 0. The j aw 109 is secured' to a collar 110 bya screw 111, as shown more clearly in Fig. 20. The-collar 110 is clampedto a shaft 112 by a cap screw-113. The jaw 108 is provided with lugs 114atA opposite sides of the collar 110 which are journaled on the shaft112. A gear segment 115 is also journaled on the shaft 112 and iscbnnected with the aw 108 by means of an arm 116 and a spring 117. Theshaft 112 is journaled in the frame 30, as shown in Fig.' 6, and isprovided with a gear segment 118 at one side o'f the frame-member 30 anda 122 which engages a plate 123 connected with the vjaw 1109 whichpermits yielding movement of .the jaw relative to the collar110. It

lis thus apparent that the jaw 109 is yieldingly connected'to the shaft112 and that the'jaw y108 is yieldingly connectedto the gear seg.- mentjournaled on the shaft 112.

A second shaft 124 is journaledin the frame .member 30 in spacedrelation to the shaft 112 and is lprovided with a. gear. segment f 125meshing with the gear segment 118.-. A gear 'msegment 126 is jouraialedon the shaft 124 at shaft 124 in a manner similar to the collar 110 ontheshaft 112. AThe jaws 128 and 129 are L position in Fig. 10. A n idlersegment 131 is journaled on a stud shaft 132 mounted on the frame 30..The idler segment 131 has a suiciently wide face to mesh with the gearsegments 119 and 126 and the segment 126 also meshes with the segment115. An operating rod133 is pivoted to the segment 118 at 134 and isreciprocated lengthwise by means of a rocker arm 135 operated by a cam136 on the main drive ,shaft 36. The operating rod 133 is provided witha spring 137 which permits yielding downward pressure to be exerted onthe rod. lVhen the rod 133 is raised from the position shown in Fig. 10to the position shown in Fig. 7, the shaft 112 will be rotated in acounter-clockwise direction and the shaft 124 will be rotated in aclockwise direction, as viewed in these figures. The aw 109 will move inunison with the shaft 112 and the jaw 129 will move in unison with theshaft 124. The movement of the jaw 129 will be more rapid than that ofthe jaw 109 because of the inequality of the radii of the gear segments118 and 125. This will move the jaw 129 out of the way of the jaw 109 sothat they will not interfere with eachother. During the upfwardmovementof the rod 133 the gear segment 119 will move the shaft 112 and willrotate the segment 131 in a clockwise direction.

Since thesegment 131 meshes with the seg-- ment 126 the segment 126 willmove in a counter-clockwise direction to throw the jaw 128 upwardly tothe open positionshown in Fig. 7. The segment 126 meshes with thesegment 115 so that this segment will move'clockwise to throw the jaw108 outwardly into the position shown in Fig. 7. In other words, both'sets of jaws are open during the upward movementof the rod 133 and byreverseactionare closed during the downward movement of the jaws. Thecam for operating the rod`133 is shaped to close and open'the ja'wsduring the pause ofthe turret, the jaws remaining open duringthesmovement of the turret. h v

Each of the jaws 108, 109, 128 and 129 is provided with a recess 138shown best in Figs. 19 and 20 for receiving the briquettes 48.Surrounding the recesses 138care gripping members 139 which clamp theprojecting edges of the wrapper l70 and squeeze the edges togetheraboutlthejbricjuettes, as shown in i these figures. The clamping members139 of the` jaws 108 and 109 are provided with heatingD elements 140which are in the form of electrical resistance wires supplied withcurrent from leads v141 which extend through the shaft 112. i

The projecting edges of the wrapper are squeezed together and at `thesame time the wax orothermaterial with which the wrapper is treated issoftened bythe heat of the ele ments 140 so that the edges of thewrapper are j sealed together, completelyl closing the vWrapper andforming an air-tight package, The

f flanges 1 folded fla At the time that the edges of the contact members139 of the jaws 128 and 129 are not heated but act as chilling devicesby means of which the melted wax is again hardened so that the flapswill not be separated by further manipulation.- The jaws 128 and 129 arereferably provided with radiation fins 142 or dispersing the vheat fromthe jaws and keeping them cool. In this way the project- 'ing edgesofthe wrapper are first heat-sealed together and thereafter chilled toinsure that the sealed parts will remain together.

'After the wrapper has been sealed `and .cured to a shaft 146 adjacentthe station at which the package is brought to rest is a creaser 147having creasing flanges 148 at each end thereof for pressing the foldedp0rtion of the wrapper against theends of the wrapped article. Theflanges 148, as shown in Fig. 15, are` spaced apart an amountcorrespondingto the length of the package so that when the creaser ismoved against the side of the package the flanges will extend adjacentthe ends of the package andpress the folded flap to a positionagainstthe end flaps.l The end flaps are later folded over the ends of thepackage and the creasing process is for the purpose of preventing vthefolded edge flap from bulging backwardly when the endlaps are foldedover. The wiper holds the edge ap in folded position; as shown in Fig.12,

.while'the creaser-147 rotates in a counterclockwise direction causingthe creasing to approach and contact. with the flanges' 148 reach thecenter line of the package the turret begins its forward movement` P andthe yturret and creaser travel together to carry-the package between theend. folders 149. The position of the package between the end foldersv149 is shown more clearly in Fig.

13 and the creases formed bythe creasing flan es 148 are indicated at'150. Y

T e lfinal movement of thepackage by the turretcarries the package to aposition diametrically opposite the first position. .In

this nal position the package is brought into alinement with an opening151 between upper Y I' and lower guides 152 and 153, respectively. Apair of discharge fingers V154, one at each side of the turret,discharge'the package from the turret into the opening 151.' The upperguide 15,2 is'provided with tapered recesses 155, one at' each side ofthe guide, for receivmain drive shaft 36. 'The lingers 154 carry.

the package entirely through the opening 151 and discharge it intogrippers 157 on a turret 158 secured toa shaftr 159. The shaft 159 isrotated in= unison with the shaft 86 by means of a gear 160 on the shaft86 and an idler 161 on a stud shaft 162. '-Ihe shaft 146 is rotated by achain of gears 163, Fig. 1, which are driven by a gear'on the shaft 164whichcar-v y ries the uppermost sprocket 165 driven by the chain 10.6.An outer wrapper 166 is inter-v posed in a guide 167 extendingtransversely of the passage 151 and this outer wrapper is folded aboutthe forward edge of the package 'as it passes through the opening 151.The 'Wrapper extends suiiiciently above the opening 151 so that the topflap of the wrapper will extend outwardly away from the package, asshown in Fig. 7. The rear face of the projectingflap is-treated with asmall amount of adhesive material by a swinging arm 168 or othersuitable pasting mechanism. The wrapper is discharged from the turret158 by a pair' of ngers 169 into a passage 170 having a spring guide 171at the top thereof. The

which folds the projectingflap backwardly against the edge of thepassage and glues the flap in place, thus placing an outer wrapper aboutthe sealed package. A magazine is provided a-t the end of the passage170 and a rolower end of the magazine and raises the l packages into themagazine as they reach the end of the passage 17.0. The camdisc 174 issecured to a shaft 175 connected by spur gears to' a -.shaft. 176which'l is provided with a sprocket 177 driven by the sprocket chain106.

The lingers 169 are carried on arms 178 which are connected by links 179to the arms 156 so that the arms 17 8l and thearms 156 are oscillated inunison with each other.

' The operation of the various partshas been explained. in connect-ionwith` the decription of the parts so that a detailed descriptionv of theoperation of the machine is thought t0 be unnecessary. Briquettes are4deposited in the hopper' 84 andare automaticallywrapped in treatedwrappers 'which are "sealed by pressing together the projecting edges ofa wrapper, after which the edges are folded against the package and aiband or outer wrapper is placed in lposition to hold the folded edges inplace. The briquettes are assembled in packages' of two briquettes each,
